Shortly after 10 on the morning of November 15, Dallas homicide detectives were called to a dead-end Oak Cliff road that runs into Cedar Creek. There, at the bottom of the creek bed, an officer on the lookout for illegal dumping found something unexpected: the body of a dead man. Initially, he was unidentified; his cause of death listed as "unexplained." Investigators didn't know how long he'd been there.

Now we know his name: Wayne Haywood Williams, a 48-year-old man whose last known address was an apartment complex on Collins Avenue, just one block from Juanita Craft Park near Fair Park -- eight miles from where his body was found. And we now know the cause of death: According to the Dallas County Medical Examiner's office, which completed the autopsy Wednesday, Williams died of "blunt force injury." The ME's office can't be more specific, not until the coroner signs off on the report and makes it publicly available some time next week.

Right now, the ME's office says the manner of death remains "undetermined." Which means they are not prepared to rule Williams' death a murder.

"They're still going to list it as unexplained right now, because they're still trying to determine" what killed him, says Sgt. Warren C. Mitchell, a Dallas police spokesperson. "The injury could have come when he fell" into the creek bed.

That said, Mitchell notes, the case remains in the hands of homicide detectives: "They are continuing to look at it."
